AISI high speed steel material M42tool steel is a molybdenum-series high-speed steel alloy with an additional 8% cobalt. (HSS Steel M42) 8% Cobalt tool bits are designed for machining work hardening alloys and other tough materials. They have increased water resistance and tool life. This improves performance and retention of the cutting edge. M42 steel composition makes for a good combination of toughness and hardness.

High-speed steel M42 steel is widely used in metal manufacturing industries and in cutting tools manufacturing because of its superior red-hardness as compared to more conventional high-speed steels, allowing for shorter cycle times in production environments due to higher cutting speeds or from the increase in time between tool changes. HSS M42 tool steel is also less prone to chipping when used for interrupted cuts and costs less when compared to the same tool made of carbide. Tools made from cobalt-bearing high speed steels can often be identified by the letters HSS-Co.

AISI M42 tool steel is a conventionally manufactured cobalt alloyed high-speed steel. The various stages of the manufacturing process are chosen and controlled so that an end product is obtained with a good structure in terms of carbide size and distribution. This is a distinct advantage for the finished tool.

APPLICATIONS

AISI M42 tool steel is a high-speed steel suitable for cutting tools such as, twist drills, broaches, taps, milling, cutters, saws, reamers etc. In terms of performance, HSS grade M42 is a steel to be used in conditions where the demand for hot hardness is of great importance i.e. where high performance is essential.

Pre heat the M42 high speed steel slowly and uniformly to 650-760°C and equalise. Then increase more quickly to the forging temperature of 1010-1150°C and equalise prior to forging. Do not allow the forging temperature to drop below 980°C, if this occurs re heating will be necessary. Always cool the m42 high speed steel very slowly after forging.

Heat Treatment of AISI M42 High Speed Material

Annealing

AISI M42 high speed steel is heated at 871°C (1599°F) and then cooled slowly in a furnace.

Stress Relieving

To relieve stresses created by extensive machining or tooling with complex geometries. Heat in a neutral atmosphere for 1 to 2 hours after reaching a temperature of 1110 to 1200°F (600 to 650°C), followed by slow cooling in the furnace.

Tempering M42 tool steel at 560°C / 1040°F or higher 3 times for at least 1 hour at full temperature is recommended.

Machinability of AISI M42 Tool Steel

AISI Steel grade M42 tool steel can be drilled, turned, threaded, broached, milled and tapped when it is in its annealed condition and rated at 45% of 1% carbon steel.
